The config looks good to me. I did have a similar problem with a RoCE
card where I could not get iSER working although RDMA did work.
Looking at the code, it seems that maybe the QLogic driver is not
properly allocating some memory that iSER is trying to use. I'm not an
expert in this so I could be completely off base here, just trying to
help out.
If you are adventerious, you can add some print statements in
drivers/infiniband/core/fmr_pool.c in the ib_fmr_pool_map_phys
function to see what may be going on. I think you are hitting this
line:
if (list_len < 1 || list_len > pool->max_pages)
return ERR_PTR(-EINVAL);
I would check the values of list_len and pool->max_pages before that.
